Abstract
Abstract A cutting-out machine for flat material such as cloth has a slit blade cutting mechanism mounted on one end of a double-arm beam. The beam arms are pivotally connected to one another about a vertical axis. The cutting mechanism is pivotally connected to one end of the beam, preferably in an adjustable spring-loaded mount. The pivot axis is vertical and aligned with the cutting edge of the slit blade. The other end of the beam is pivotally connected, also along a vertical axis, to a carriage that rides on guide tracks extending along a longitudinal edge of a support table for the material. The carriage is preferably driven by an electric motor under the control of a switch located on the cutting mechanism. The beams arms are substantially equal to the width of the support table when the beam is fully extended.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
183 words
A cutting-out machine for flat material, especially a cloth cutting machine, comprising in combination: a support means for the flat material; guide means mounted lengthwise of that support means; a beam positioned above that support means and pivotable around a vertical axis being mounted on a carriage which is movable along the guide means lengthwise of that support means, that beam having at least two arms which are interconnected by a joint having a vertical joint axis, a first one of that arms being pivotable around the vertical beam axis and a second one of that arms having a free end opposite to its end interconnected with that first arm; a cutting mechanism mounted at the free end of that second arm and being pivotable around a vertical axis being substantially coincident with a cutting edge of a cutter element of that cutting mechanism; the length of that first and second arms being such that the entire length of that completely extended beam is substantially equal to the width of that support means in a direction perpendicular with respect to that guide means.
Claim 2
Dependent Claim
183 words
A cutting-out machine for flat material, especially a cloth cutting machine, comprising in combination: a support means for the flat material; guide means mounted lengthwise of that support means; a beam positioned above that support means and pivotable around a vertical axis being mounted on a carriage which is movable along the guide means lengthwise of that support means, that beam having at least two arms which are interconnected by a joint having a vertical joint axis, a first one of that arms being pivotable around the vertical beam axis and a second one of that arms having a free end opposite to its end interconnected with that first arm; a cutting mechanism mounted at the free end of that second arm and being pivotable around a vertical axis being substantially coincident with a cutting edge of a cutter element of that cutting mechanism; the length of that first and second arms being such that the entire length of that completely extended beam is substantially equal to the width of that support means in a direction perpendicular with respect to that guide means.
Claim 3
Dependent Claim
14 words
A cutting-out machine according to claim 1, wherein the carriage has an electric drive.
Claim 4
Dependent Claim
27 words
A cutting-out machine according to claim 2, wherein a control device for the electric drive is positioned at the extremity of the beam adjacent the cutting device.
Claim 5
Dependent Claim
